Polysaccharides are complex carbohydrates composed of long chains of monosaccharide units linked together by glycosidic bonds. These long-chain polymers can be either linear or branched, and their specific structure determines their properties and functions. Common monosaccharide units found in polysaccharides include glucose, fructose, and galactose.

The classification of polysaccharides can be based on their composition or function. Homopolysaccharides are made up of only one type of monosaccharide, such as starch and cellulose, both polymers of glucose. Heteropolysaccharides, on the other hand, are composed of more than one type of monosaccharide unit.

Functionally, polysaccharides play vital roles in living organisms. In plants, starch serves as a primary energy storage molecule, while cellulose provides structural support to cell walls. Animals store glucose in the form of glycogen, primarily in the liver and muscles, as a readily available energy reserve. Chitin, another important polysaccharide, forms the exoskeletons of insects and crustaceans, as well as the cell walls of fungi.

Polysaccharides also have significant applications in various industries. They are used as thickeners, emulsifiers, and stabilizers in food production, as well as in the pharmaceutical and cosmetic industries. Their biodegradability and renewable nature make them attractive alternatives to synthetic materials. The study of polysaccharides, known as polysaccharide chemistry or glycobiology, is a complex but important field within biochemistry.
